After being nearly
eradicated by trappers
in the mid-1800s,
beavers (left) are making
a comeback in the West,
including in Grand Teton
National Park. As climate
change creates more
variable weather, these
wetland engineers are
holding more water in
the landscape, thereby
bolstering biodiversity.
The two-way traffic
captured by a camera
trap along a busy game
trail above the Buffalo
Fork River near Grand
Teton (right) includes
a cougar, a black bear,
and a mule deer.
